ANSI stands for "American National Standars Institute"
PN 20 is equal to ANSI 150 & ANSI 300 equals PN 50.
The latest ANSI standard is C99. See the attached link.
C is a programming language and ANSI is the standardization committee. The C language is under the auspices of the ANSI committee, which monitors the grammar and structure of the language in a standard way that compiler writers must adhere to. ANSI C means that it is a standardized version of the C language according to the rules of the committee and should work/compile the same way on any system that uses an ANSI C compliant compiler.
ANSI valves are based on American National Standards Institute Standards. For example, ANSI 16.34 refer to steel valves. BS valves are based on British Standards. For example, BS1212 refer to ball valves excluding floats.
Scalable Processor ARChitecture
Knowing that: 1. No version of Windows in recent history has been written for SPARC processors. 2. SPARC processors are expensive. You'll never see them on a Wal-Mart shelf. 3. The x86 architecture is the most popular architecture for computers. 4. Windows is the most popular operating system You most definitely have a computer with an x86 processor.
this is the user view of the database, where the customer interacts with the database through the help of graphical user interface (GUI) Benny Pah
A reference architecture consists of:Set of global external schemas.Global conceptual schema (GCS).Fragmentation schema and allocation schema.Set of schemas for each local DBMS conforming to 3-level ANSI/SPARC .Some levels may be missing, depending on levels of transparency supported.Can be homogeneous or heterogeneous.Gaurav SinghG.N.I.T MCA,GREATER NOIDAContact: 9458660007
SPARC was created in 1985.
The Architecture Design Process ultimately links with the Implementation Process or the Integration Process
The acronym SPARC stands for several things. Among them are Scalable Processor Architecture, Scholarly Publishing and Academic Resources Coalition, Standards Planning And Requirements Committee, Support Personnel Accountability Report Card, Single Person Armed Racing Craft, and more.
The ANSI-SPARC Architecture, where ANSI-SPARC stands for American National Standards Institute, Standards Planning And Requirements Committee, is an abstract design standard for a Database Management System (DBMS), first proposed in 1975 .A standard three level approach to database design has been agreed.- External level- Conceptual level- Internal level (includes physical data storage)The 3 Level Architecture has the aim of enabling users to access the same data but with a personalised view of it. The distancing of the internal level from the external level means that users do not need to know how the data is physically stored in the database. This level separation also allows the Database Administrator (DBA) to change the database storage structures without affecting the users' views.External Level (User Views)A user's view of the database describes a part of the database that is relevant to a particular user. It excludes irrelevant data as well as data which the user is not authorised to access.Conceptual LevelThe conceptual level is a way of describing what data is stored within the whole database and how the data is inter-related. The conceptual level does not specify how the data is physically stored.Internal LevelThe internal level involves how the database is physically represented on the computer system. It describes how the data is actually stored in the database and on the computer hardware.Most modern commercial DBMS are based on this system. The ANSI-SPARC model however never became a formal standard.
The ANSI-SPARC Architecture (American National Standards Institute, Standards Planning And Requirements Committee) is an abstract design standard for a DBMS, first proposed in 1975. Most modern commercial DBMS are based on this system. The ANSI-SPARC model never became a formal standard. The objective of the three-level architecture is to separate the users' view(s) of the database from the way that it is physically represented. This is desirable since: * It allows independent customised user views. ** Each user should be able to access the same data, but have a different customised view of the data. These should be independent: changes to one view should not affect others. * It hides the physical storage details from users. ** Users should not have to deal with physical database storage details. They should be allowed to work with the data itself, without concern for how it is physically stored. * The database administrator should be able to change the database storage structures without affecting the users' views. ** From time to time rationalisations or otherchanges to the structure of an organisation's data will be required. * The internal structure of the database should be unaffected by changes to the physical aspects of the storage. ** For example, a changeover to a new disk. * The database administrator should be able to change the conceptual or global structure of the database without affecting the users. ** This should be possible while still maintaining the desired individual users' views. with kind regards M I K

There are 24 registers per set, with an overlap of 8 with the levels on either side of the set. · N = 8 + 16 * K
Conceptual database design is the process of constructing a model based on the enterprise. Logical database design is the process of constructing a specific data model. Physical database design is the process of producing of the database on the secondary storage.
